To all whom it may concern:

Be itknown that I, 'Fonns'r H. Mom'- coim'ar, a citizen of the United States, residing at East Orange, county of Essex, and .State of New Jersey, have invented certain new and useful Improvements-in Attach ments for Adding-Machines and Type- \Vriteis, of which thefollowing is a specification.-- 4

This invention relates to attachments for adding machines and typewriters. The present improvements are, adapted for use on adding machines, typewriters, combined adding machines and typewriters, andother machines generally 7 similar thereto.

The present invention is designed to facilitate the posting of a continuous ledger sheet and a separate bill or statement to the end that the statement discloses only the transactions of the current month and their transcription in duplicate on the ledger sheet so that both entries .are made. at the same time by the machine, due to the interposition of a sheet'of carbon paper. The entries for the current month, or any particular month, may require only two or three lines and it has been proposed heretofore in mechanical posting devices to rovide for the foldover statement and let get sheet for this work, thus necessitating a new lmlgclishcct for each new'statemcnt sheet. By the use of a-scparate statement sheet or bill and a separate ledger sheet, a single ledger 'shcct may be used month after month, accumulating items from time to time, until it is entirely covered with entries struck through a carbon sheet when the eutrics are placed on successive statements entered from time to time to show the different months transactions.

The present improvements are .particularly designed for facilitating, combined .--.tatemcnt and ledger sheet posting, although I wish it understood that they are not restricted to such use and that the different improvements utilized in the work hereinafter set forth may be independently, or jointly, used for other purposes on type: writers, adding machines, combined adding machines and typewriters, bill posting or statement making machines and all other machines analogous thereto and I do not limit myself to the uses hereinfter specified nor otherwise than as pointed out in the respcctive claims.

Application filed Hatch a0, 1916. Serial No. 87,314.

In practice, a ledger sheet is usually wider than the statement sheet and the position on the ledger sheet for a-given entry is usually on a different line, ordinarily higher up, considered from-top to bottomof the sheet, than a line on which the given entry should appear on the statement. As heretofore practised, the operator has to meet this condition of two sheets of paper of difi'erent widths and a carbon sheet of a width different from the ledger and statement sheets and, also, the necessity for making the entry at different positions, higher or lower, on the two sheets and that the cat must follow the preceding entry on ea given sheet. a

To meet these conditions, it is necessary to alinc. vertically the ledger sheet and then to properlyalino vertically the statementsheetso that the vertical column lines on the two sheets will exactly register, even though a carbon sheet is between the ledger sheet and stateme ntsheet. It is also acces sary to ascertain the line of entry of the ledger sheet and then shiftthe statement sheet upwardly or downwardly, as the may be, to a corresponding line for. entry on the statementsheet. As the last visible part of each entry is usually made on.the extreme right ma :gin of the statement sheet,

heretofore this line of entry would be iii-- visible on the lager sheet as it will beentircly covered up by the statement sheet and carbon sheet so that the preceding entry is concealed.

The present improvements overcome the foregoing diilicultics by the provision, first, of means for automatically printing on the ledger sheet at the right of the margin of the statement sh act 'a line or other indicia which indicates the last line of entry on thelcdgor sheet 50 that this iudicia or line is exposed and serves as a guide for the up and register with the corresponding lines on the ledger sheet despite the fact that these latter lines are covered by the carbon sheet. To that end, I provide an improved means constituting a secondary vertical alinement guide which constitutes an abutment for either the right-hand 'or left-hand margin of the statement sheet.

My improved secondary vertical alinement guide may be used in connection with the platen of anv writing machine,'adding machine, or number printing or other like machine by itself and it may be combined, relatively adjustable or otherwise, with any preferred or ordinary paper guide on the carriage. This secondary vertical alinement guide may be combined with, or used separately from, a paper fingerand if used therewith, may be connected thereto or mounted separate therefrom; o'iher modifications could be resorted to, as I 11.1 the first, so far as I am aware, in nrowble a vertical aline ment guide, serving as u! abutment for the margin of the paper and disposed adjacent to the platen for that purpose, whether such abutment alinement guidebe stationary, adjustable, attached to, or combined with, a paper finger guide.

So far as I am aware, I am the first to provide means for printing, in off-set or spaced relation to the printing section of a number printing device, an indicia printer, whether the same operate simultaneously with the number printing device or not. Furthermore, I believe myself to be the first to provide a spaced or separated indicia or sign printer so related to, Mid combined with, a vertical paper alinement guide that the number will be printed on one side of said guide and the indicia, sign, or symbol, printed on the other side of said abutment paper guide to the end that, in effect, the printing is split on opposite sides, considered horizontally, of said abi tm'mlpaper guide and which results in the .mmoer being printed on the outer and narrrwer sheet, such as the bill or sta temenl. sheet, and the sigin-symbol, or indicia being printed on the rear or ledger sheet for purposes of line identification.

The showing of the invention in the accompanying drawings, and the description thereof hereinafter appearing, are illustrative, rather than restrictive, of the scope thereof, as the invention is susceptible of various modifications.

In the accompanying drawings:

printing section of an adding machine, or a combined adding machine and typewriter, as will illustrate the application of the present improvements and their use;

Fig. 8 is a detailperspectivc of a vertical alinement paper guide connected to a paper finger; and

Fig; 9 is a vi paper guide alone.

Referring first to Fig. 1, 1. is a. part ofthe carriage, 2, the platen, 3, the table orpaper support and 4, the ribbon and ribbon reel, all of which may be of any construction. The usual rubber rolls which pres the paper against the platen, are controlled by the finger-piece 5. The rear paper guides 6 and 7 lie on the'paper support or table 3 and are adjustable" independently of. each other locked thereto by means, not shown, adapted for release or setting by the Either one, or both, of these paper guides may be used in the operations hereinafter set forth. Carried by the carriage 1 adjacent the platen' 2,-is a bar or-strip 9.

The secondary or vertical alinement paper guide shown in Figs. 1, 2, 8 and.9, is provided \yitha flap or abutment face 10 and a base 11,the latter being engaged with thobar 9 and preferably slidable lengthwise thereon cw of the vertical alincment ICC 'lengthwise of saidtablc or support and devices 8.

and frictionally or otherwise engaged therewith so that the said paper guide will be, or-' may be, held at any point to which it me be adjusted on the bar 9, My invention is l not limited, however, in this respect, to. a

paper guide which is adjustably mounted,

but consists, broadly, of a vertical alinement paper guide adapted to serve as an abutment for the margin of the sheet, whether the paper guide be used at the right or the left of said sl|eet.- A portion of the edge may be curved as at 12, so as to conform closely, without touching, to the platen 2 and the papers thereon without, however, interfer ing with the part 10 serving as an alining abutment for the edge of the paper. I may combine with the paper guide 10 a paper finger which may be positively connected thereto, as shown at 13 in Fig. 8, or which 6 may be an entirely separate device, either stationary or adjustable, and, the paper guide may be used with or without the use of the paper finger 13. In Fig. 9, I have shown the paper abutment guide 10 alone. 1 The paper guide 10, or may be pro vided with an alining edge 14 which can be used in connection with the usual scale or straight edge on the machine for horizontal alinement where the type strike on the paper. 1

Referring to Fig. 1, and to Fig. 6, I have shown printing segments constituting, considered generally, a number printing sec tion 15 such as used, for instance, on the well-known Ellis adding machine. These printing segments are adapted to strike the paper as shown in Fig. 6, when the carriage is in proper position and willthen deliver their imprint at the left of the' paper guide 10 to print upon the statement sheet the total or item. Heretofore it has been proosed to provide a signal or symbol printer in connection with these printing segments and in other machines signal printers have been used with other number printing devices. My improvement in that respect consists in providing a sign, signal, or symbol printing device 16 which is oil-set or spaced laterally away from the printing section 15,

as shown in Fig. 6, so that it will print to the right of the paper guide 10, whereas the printing segments will print to the left thereof, thus, -in effect, bringing about a split in theprinting and causing the number to be printed on'the statement sheet and the sign or symbol which is indicated at 17 to be printed on the ledger sheet. So far as I am aware, I am the'first to provide means for this purpose whether the number printing and symbol printing devices be considered alone, or, combined with the paper guide such as generally shown at 10. This symbol printer and the splitting of the printing overcomes the defect heretofore existing and affords an absolute guide, for purposes of line identification, despite the fact that the previous entry on the ledger sheet is completely covered.

Assuming that the work to be performed merely contemplates the use of aledger sheet 18, a statement sheet 19 and carbon sheet 20, these are first associated to aline the sheets along the top and left hand edges, as shown in Fig. 3. The sheets are then inserted in the machine, using the right-hand paper guide 6 on the back of the carriage to cooperate with the right-hand edge of the ledger sheet 18. The sheets are then turned up to the position shown in Fig. 1. The symbol or sign 17 indicating the line of last entry on the ledger sheet being exposed and plainly visible, the platen is turned so. that the part 14 is opposite this line. There is now a vertical and horizontal alinement of the wider or ledger sheet 18. The statement sheet 19, however, is too far to the left and not in proper horizontal alined position, because the statement sheet 19 usually has a deeper heading 'th in the ledger sheet and corresponding horizontal lines would, therefore, be below correct positions on the ledger sheet. The statement sheet 19 is consequently taken hold of and drawn up to the position of the ordinary commonly used horizontal line guide on the carriage, the lever 5 having been moved to release the gripping of the paper so that this shifting of sheet 19 can be cbtained. When pulling the sheet 19 vertically, it is also shifted latorally to bring its right-hand margin against the paper guide 10. This having been done, as shown in Figs. 2 and 4, the statement sheet 19 is thus vertically and horizontally alined so that its registration with the ledger sheet 18 will be accurate. The pressure rolls controlled by the lever 5 are then thrown into holding position so that the sheets 18, 19 and 2C are securely heldto the platen, as in Fig. it.

As shown in Fig. 4, the sheets'are in proper position for the next entry, the balance on the old account having been previonsly printed by the printing section 15 on the first line of the statement, as shown in Figs. 2, 4 and 7 which also prints the sign 100 17 if not already appearing on the ledger sheet. It ill be noted that the last entry on thestatement sheet, which is also struck through to the ledger sheet, is $500 in the charge column and $500 in the balance 001- 105 umn with the marl: 17 printed only on the ledger sheet 18 at the right and directly opposite the balance column.

In Fig. 5, .the sl eet shows a second entry for the eurrentmonth and the new balance 11a! and also the printing of the mark 17 on the ledger sheet 18 which will thus indicaie the position for the next entry on the ledger sheet when the latter is put into the machine at some future date.
